I recently completed a three day worked with Christine Bossler, where she taught the making of Chasing & Repouse tools. We learned to take different thicknesses of tool steel rods and shape them into the desired shapes using files. Once we had our desired shapes we refined them using sand paper and sanding wheels. Then polished the working edges to a shine. When we were satisfied the tools were ready, we heat treated them (hardening and tempering) for use. Four types of tools were covered: Lining, Pushing, Planishing and Texturing. I the picture you see three types of tools I made. The left two are examples of Liners, the middle one is an example of a texturing tool and the right two are examples of Pushers.
